I wouldn't just give away everything. Use the executive summaries as a sales tool. Make a note that for any of these startup ideas you're willing to serve as a minor stakeholder (say, 10%). That would 1. allow you to gain something from someone executing on your idea, and 2. allow the people who executed on your idea the benefit of having your brain involved in the development process. The ideas are yours and you know them better than anyone else. You've had them longer than anyone else, and you've thought about them longer than anyone else. It makes sense for you to be involved to some degree because you have far more to contribute than just a few sentence concept overview. It would be a win/win for all. If they are truly good ideas, it would be a shame to just give them away. They are your children and you their parent (that's how I feel about my ideas, at least!). Stay around. Stay involved. Watch them grow. Be a part of it!
I was debating putting the first idea in this post, but I thought it would be confusing.
Separately, I'm experimenting with email lists to help promote blog posts. It is related to content marketing experimentation for my startup. Read more here: http://blog.yesgraph.com/post/63562259689/first-1000
The problem with twitter is that it isn't nearly enough space to explore even the basic boundaries around an idea. This means most ideas on twitter are vapid. Just my opinion
1. Bravo, this is a really well-done content-marketing campaign. It's original/greenfield, provocative, interactive, and you intentionally made your idea list screen-shot so low resolution it's impossible to read unless we tune in :)
2. Broadly I agree with you open-sourcing ideation does a lot more benefit than harm. I have a similar list that frustratingly keeps getting rows added where I'd rather see an idea validated by someone else's execution than die on the vine.
Ideas may be easy, but good ideas are incredibly hard to find.
If implementation is so difficult, outsource to me! Give me your executive summary, 20 grand, and a 20% stake, and my team and I can have your project implemented in under 6 months. I'll call it the HN 20/20/6 deal. (I'll do it for 10 grand if I think the idea really has potential.)
I've thought about doing this too (a "dev-venture" model), but unfortunately I haven't found the time to flush it out legally or look for good deal-flow. Maybe one of us should write a blog post about our concept in case someone else wants to execute on our good idea :)
